2015 statistics on murders and police killings in USA: Police killings: 986. Of these, 495 of those killed were white (50%), 258 were black (26%), 172 were Hispanic (17%). Murders: 15,696 total, of which 52% of victims were black, and in these cases over 90% of the perpetrators were black.

“Do White Police Officers Unfairly Target Black Suspects?” Abstract: “Using a unique data set we link the race of police officers who kill suspects with the race of those who are killed across the United States. We have data on a total of 2,699 fatal police killings for the years 2013 to 2015. This is 1,333 more killings by police than is provided by the FBI data on justifiable police homicides. When either the violent crime rate or the demographics of a city are accounted for, we find that white police officers are not significantly more likely to kill a black suspect. For the estimates where we know the race of the officer who killed the suspect, the ratio of the rate that blacks are killed by black versus white officers is large — ranging from 3 to 5 times larger. However, because the media may under report the officer’s race when black officers are involved, other results that account for the fact that a disproportionate number of the unknown race officers may be more reliable. They indicate no statistically significant difference between killings of black suspects by black and white officers. Our panel data analysis that looks at killings at the police department level confirms this. These findings are inconsistent with taste-based racial discrimination against blacks by white police officers. Our estimates examining the killings of white and Hispanic suspects found no differences with respect to the races of police officers. If the police are engaged in discrimination, such discriminatory behavior should also be more difficult when body or other cameras are recording their actions. We find no evidence that body cameras affect either the number of police killings or the racial composition of those killings.”

There were 6,095 black homicide deaths in 2014—the most recent year for which such data are available—compared with 5,397 homicide deaths for whites and Hispanics combined. Almost all of those black homicide victims had black killers. Police officers—of all races—are also disproportionately endangered by black assailants. Over the past decade, according to FBI data, 40% of cop killers have been black. Officers are killed by blacks at a rate 2.5 times higher than the rate at which blacks are killed by police. Some may find evidence of police bias in the fact that blacks make up 26% of the police-shooting victims, compared with their 13% representation in the national population. But as residents of poor black neighborhoods know too well, violent crimes are disproportionately committed by blacks. According to the Bureau of Justice Statistics, blacks were charged with 62% of all robberies, 57% of murders and 45% of assaults in the 75 largest U.S. counties in 2009, though they made up roughly 15% of the population there.
